Release Notice: LoadMaster LMOS 7.2.59.0 GA

Updated: 

Release Notice: LoadMaster LMOS 7.2.59.0

Release Date: 27 March 2023

LMOS 7.2.59.0 is a feature and bug fix update for the General Availability (GA) release branch, made available on 27 March 2023.  Notes related to installing the image and a brief content listing are provided below. For full details on all the new features and updates provided, consult the LoadMaster 7.2.59.0 Release Notes.

Upgrade Patch XML File Verification Notes

By default, verification of the digital signature on upgrade images is required in LMOS 7.2.50 and above. See the Update Verification Options setting under System Administration > Miscellaneous Options > WUI Settings. If the unit you are upgrading is set to require validation, you'll need to supply the XML Verification File supplied with this release.

Note that:

  • In previous releases, two verification files were provided: one for pre-7.2.51 systems and one for later systems. This restriction has been removed with this release; use the same XML file regardless of the LMOS version from which you are upgrading.
  • LoadMasters running an LMOS version prior to 7.2.49 do not provide the option of XML file verification in the UI or API. If you are upgrading from one of these releases to this release, you can verify the digital signatures offline using a manual process documented on the support website.

If you are currently running LMOS 7.1.x or an earlier version, please see the article Kemp LoadMaster Firmware Upgrade Path for full upgrade path information.

Downgrading to Earlier Versions:

Downgrading a LoadMaster running LMOS 7.2.56.0 to LMOS 7.2.51 (or a later release) can be performed using any desired Update Verification Options setting.

Downgrading to LMOS 7.2.50 or a previous release can only be done when the Update Verification Options setting is set to Optional or Legacy. When performing the downgrade, do not specify an XML file. If you want to verify the digital signature on the image before downgrading, you can do so using a manual process documented on the support website.
